a Probability densities (P) for the shear stress τ for the typical system evolution at a normal pressure of 1 GPa. Colored lines show χ2-fits of gaussians to the probability densities. b Average shear stresses determined from the Gaussian fits to the densities as a function of the number of water molecules for normal pressures of 1, 3, and 5 GPa. The colors of the discs distinguish the different regimes, while the disc size indicates the probability of a regime.
